Question about LG French Door Cabinet Depth Refrigerator 21 Cu. Ft. - LRFC21755

3 Answers

LG refrigerator makes loud noise and then stops running.

The frig makes a loud grinding noise that comes from the freezer. Sometimes the frid just stops, with error codes, and I have to cycle the power.

Seems related to humidty as I can usually make the noise go away by blowing warm air in the vents at the back of the freezer, melts ice on a motor or fan?

    Same problem of icing. LG is aware of this and I understand that they have redesigned the circuit board to delay 15 minutes before restarting the freeze cycle to help avoid the problem. Now the trick is to get LG to supply the updated circuit board.

    LG Refrigerator model LFD 25860, bottom freezer is a lemon. I purchased it 1 1/2 yrs ago and from the first day it was delivered to my home there was problems. It started with the water despenser, a couple of weeks later it was the ice maker, than a month after that it was the freezer. Ice build up and not cooling enough. Now only after 1 1/2 yrs and after paying $2,000 for this refrigerator it stopped working, it broke. I have had serveral repair men come in and try and repair this Junk and it keeps breaking down, now it broke completely. I will never buy an LG product again, it was my first and it will be my last. I have contacted LG customer service and they are not willing to help. Basicly their attitude is , it is my problem not theirs.

You are seriously frozen up. Defrost the unit completely. Then, be aware that 'window shopping', leaving uncovered liquids in the box and poor door sealing (too heavy a load on the door ... too much on shelves) can cause condensation. Defrost with hot air or leave unplugged and open for about 2 days. You'll see alot of water come out.

OK, loud noise, error code, and poor ice machine performance...I had all three on my 25 cf french door LG frige. After I found out that 'Er FF' was a code for the fan motor, I took out the freezer drawers and found that the panel at the back of the freezer was not seated at the top. It was sagging and the fan motor was not being held up to the exhaust port above it...it was just blowing air in circles instead of through the refrigerator. I was able to push the panel at the top and get it to seat. Now it's MUCH quieter and seems to work better too.

Fridge had been making squeaky high pitched noises for months. Sounded like crickets. Today it was making a very loud grinding noise. Unscrewed rear lower panel and checked the fan-when I stopped the fan blade from turning the noise stopped. So I put some Teflon lubricant on the metal shaft connecting the fan and it is super quiet now.

GE side by side Refrigerator makes LOUD SQUEAK when running


Noise can come from these areas:
The inside of the freezer Self-defrosting refrigerators use a circulating fan to move the air through the freezer and refrigerator compartments. This fan runs whenever the unit is cooling. The fan is located in the freezer, as follows:

  • If the freezer is on top, the fan is on the back wall, near the top or bottom, in the center of the freezer.


  • If the freezer is on the bottom, the fan is on the back wall, near the top of the freezer.


  • If the freezer is on the left, the fan is on the back wall, halfway up or near the top.


Over time, the fan may become noisy--usually making a chirping or squealing sound, though it may make a loud groaning noise instead.

To find out if the fan is causing the noise, just open the freezer door and push in any fan/light switches. If the noise is louder when the door is open, the evaporator fan motor is the cause. You can't lubricate or repair this motor. You must replace it.

The outside back of the refrigerator There are three components on the outside back of the refrigerator that may become noisy: the compressor, the condenser fan motor (if self-defrosting), or the defrost timer (if self-defrosting).

  • The compressor is a football-sized case with no apparent moving parts. You can see it on the outside of the refrigerator at the back near the bottom. It is usually black and has black or copper-colored tubes and various colored wires attached to it. If the compressor is the device making noise, there is probably no repair that will reduce the noise. You will have to replace it--which can be quite costly.


  • If the condenser fan is making noise, there may be a build-up of lint or other debris on the fan blade. The fan is located near the back of the machine, sometimes behind a thin panel. To clean it, first unplug the refrigerator, remove the thin panel, and use a soft bristle brush to clean it. If there is no lint build-up or debris on the blade, you will have to replace the motor.


  • The defrost timer is often located at the bottom of the refrigerator, near the front and behind the kick plate. Occasionally the electric motor inside the timer may become noisy. The timer must be replaced to solve this problem.


The bottom of the refrigerator Noises detected at the bottom of the refrigerator almost always originate from the back of the refrigerator. However, sometimes the drain pan under the refrigerator will rattle. You may need to tape the pan in place to stop a rattle. Also see the “Outside back of the refrigerator.”

Freezer section evaporator fan motor bearing are going out. This would be indicted by a high pitched squealing noise. Have the fan motor replaced and it should solve your problem.

I own an LG up right refrigerator with the freezer on the bottom. The unit is about three years old and we have been very happy with the frig. Lately the unit has been making a loud fan winding noise....


  • i would just replace the fan motor $40
  • they have bushings in them that sometimes make noise when the motor shaft moves to a certain position. when you open the door it disrupts the airflow of the refrigerator and the motor shaft will go to a different position causing the noise to stop.
